Adjustable Belt-Segment Back Support for Seat Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back support devices for seats often fail to provide adequate relief for lower back pain due to being either too heavy, restrictive, or lacking proper alignment, and current lumbar supports in vehicles often have insufficient adjustment ranges to accommodate all users.
Innovation Solution
A back support system comprising two elongated belt segments with Velcro strips and elastic straps that can be adjusted to fit any size user, providing customizable support by wrapping around the torso and securing to the seat with a strap, allowing for flexibility and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wrap-type or solid support fixtures are used to provide back support, then back support and alignment are improved, but the device becomes heavy and restricts movement
Solution Approach 1:
The patent employs thin, flexible belt segments instead of heavy solid fixtures. These belts wrap around the torso and can be easily adjusted or removed, providing back support while maintaining movement freedom. The flexible nature of the belts allows them to conform to the user's body without restricting natural motion.
Solution Approach 2:
The back support device is divided into multiple separate belt segments rather than a single solid structure. This segmentation allows each belt to independently provide support at different locations along the spine, while the modular design makes the overall device lighter and more adaptable to movement.
2Adaptability or versatility
If adjustable lumbar supports with internal mechanisms or pump-up bladders are used, then support thickness and firmness can be adjusted, but the device becomes complex and heavy
Solution Approach 1:
The patent achieves adjustability by changing the number of belt segments used rather than incorporating complex internal mechanisms. Users can add or remove belts to adjust support thickness and firmness, providing versatility without increasing device complexity. This approach allows different levels of support to be achieved through simple additive configuration.
3Ease of manufacture
If fixed-thickness lumbar supports are used in seats, then manufacturing is simplified, but they cannot accommodate users of varying sizes
Solution Approach 1:
The lumbar support system is divided into multiple standardized belt segments that can be combined in different quantities. Each individual belt is simple to manufacture with fixed dimensions, but by allowing users to combine different numbers of these standardized segments, the system accommodates various user sizes and support needs without requiring complex variable-thickness manufacturing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively relieves pressure on the upper and lower spine, minimizing discomfort and accommodating users of varying sizes by providing adjustable and flexible support that substitutes for weakened core strength, ensuring comfort during extended sitting periods.
Implementation Method 1
The first elongated belt segment and the second elongated belt segment are adjoined with four elastic straps
Implementation Method 2
The first elongated belt segment is formed of a first fastening end, and a second attachment end
Implementation Method 3
The first elongated belt segment is formed of a first fastening end, and a second attachment end

AI summary
An improved back support designed for use in a seat, to relieve pressure on the user's back. The improved back support includes a first elongated belt segment and a second elongated belt segment. The first elongated belt segment is formed of a first fastening end, and a second attachment end, and the second elongated belt segment is formed of a first fastening end, and a second attachment end. The first elongated belt segment and the second elongated belt segment are adjoined with one or more straps. An individual strap is suspended from the seat to hold the brace in position and when it has been released.
